  1. I would like to see Tesla using hydraulics for ride height, suspension control, brakes and steering. This removes the following - Brake booster not needed Suspension legs do not wear out and can be individually controlled. Pressurised gas springs can be refilled. Steering gives proportional control Brakes use recirculating mineral oil no corrosion issues. Brake mechanics are smaller (less unsprung weight). All powered by a small hydraulic pump and pressure accumulator. Use two pumps for redundancy and you don’t need the accumulator.

  2. Reginald Mitchell the Supermarine Spitfire designer said that competent engineers should be able to explain how things work and what they do in simple terms. He refused to employ anyone who could not do this.

  3. Back in the 1990s, the German motorcycle manufacturer MZ commissioned a British designer. He used three aluminium castings for steering and rear suspension mount joined with aluminium tubes bonded into the castings. The company welded the joints because they refused to believe the adhesive could do the job. They failed on costs but worse the welds caused the tubes to mis-align. Some welds cracked in use causing warranty problems. The company refused to consider new technology and went broke as a result.

  4. Why does an electric car need a huge engine bay at the front?
